LEONITJAS NORZAGARAY, OF LONDON, ENGLAND.

APPARATUS FOR TREATING LATEX AND SHEETING THE COAGULATED-PRODUCT.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed December 17, 1913. Serial No. 807,213.

To all whom it may concern:

Be it known that I, LEONIDAS NORZAGARAY, a subject of the King of Great Britain and Ireland, residing at 19, Richmond street, Old Street, London, England, have invented an Apparatus for Treating Latex and Sheet ing the Coagulated Product, of which the following is a'specification.

This invention relates to an apparatus by means of which rubber milk or latex may be subjected to the coagulating action of suL- pletely coagulate all kinds of rubber milk or' latex and turn same out in sheet form, in one operation.

Referring to the accompanying drawings:-Figure 1 is-a vertical section of the apparatus, showing the various parts assem- Fig. 2 is a detail sectional view of part ofone of the sections, showing a drum revolubly mounted in the walls thereof; Fig. 3, is an enlarged vertical section of one form of top section, with another section below, and Fig. 4: a similar view of the bottom section and firepot.

The apparatus consists of a suitable firepot a for providing the necessary smoke, and a chimney A consisting of one, two, or any desired number of hollow metal sections bof rectangular or other suitable shape each section fitting over the one beneath, and being removable' The bottom section has a flan e at its lower end and is fixed to the top 0 the firepot a by means of bolts passing through holes in said flange. Any other suitable fixingmeans may be employed. A revoluble metal drum 0 with flanged ends d, is mounted in the frame 6 of each section except the top one and each of these drums in the sections intermediate of the top and bottom sections has an adjustable scraper f arranged at any desired point around the lower part of its periphery. These drums maybe mounted centrally, so that the drum ofrone section is immediately above that in the section below, or they may be mounted toward the left hand side of one section, and toward the right hand side of the section below, and so on alternately. The axles g of the drums -pro ect through the frames and are rotated by chain driven cog.

wheels, such as h, fixed thereto, or by pulley wheels, operated by ropes or bands, or by other suitable means. Said rotating means. may be actuated by hard, or by mechanical power, and may be sr. arranged as to drive the successlve drums of the sections arranged between the top and bottom sections, in opposite directions, as shown by the arrows. Alternatively the drums may all be driven in the same direction, or two drums may be driven in the-same direction. The top section of the chimney is provided with a cap or cover, z', fitted with an outlet 9' for the smoke, a portion of the said cap or cover forming a feeding hopper k, for the latex. If desired, the smoke outlet may communicate with suitable ,apparatus for recovering the valuable by-prpducts of the smoke. The

bottom section ofithe chimney has a combined scraper and chute attached to one side thereof (not shown in the drawings) for scraping the rubber off the drum and conveying it away to a suitable receptacle, or to another machine, for further treatment. Alternatively, the bottom section has adjustable pressing rollers Z 1 preferably corrugated, mounted in the sides thereof. A scraper (not shown in the drawings) is provided for scraping the rubber ofl the drum and causing it to pass between the pressing rollers, or, if desired, the roller Z may be brought into contact with said drum and thus serve a's a scraper. The rollers 1,1 press the rubber into sheet form and the sheet is led out at the side of the section by means of a suitable guide or chute This guide or chute is adjustably mounted on the frame of the section by means of the hinge 1' and set screw 8 with lock-nut t, so as to take up the wear on its point 11. which is in contact with the roller Z.

Baflle plates, such as 0 are provided in each section, except the top one, for guiding the main portion ofthe smoke around that portion of the drum in the section above on which the latex or rubber is descending.

It is to be I understood that all the 'sections between the top and bottom one are chimney made in one piece to contain any desired number of drums, scrapers, and battle plates, provided at suitable intervals.

In an alternative construction the upper lows: The firepot a is charged with suitable fuel, which is ignited. As soon as the smoke in the chimney A becomes sufficiently dense, the drums c are rotated, and latex alone-or latex and any suitable liquid for assisting coagulation-is poured into the feeding hopper it} which conveys it on to the first drum oralternatively-the rollers 2, p around which it passes until it comes in contactwith the scraper or scrapers f by which it is removed and caused to fall upon the second drum. This action is repeated until the rubber reaches the bottom drum, from which it is removed by the side scraper (not shown) and conveyed down the chute, orin the alternative constructionremoved by the roller Z and carried between same and the other roller P, the resulting sheet being led out of the machine by the guide or chute m. Claims 1.
